From RGBD image to hologram

We propose an approach to produce computer generated holograms (CGH) from RGBD data. Being able to produce CGH from RGBD images simplifies the recording process and results in more realistic reconstruction. A multilayer wavefront recording plane method is described for fast wave propagation, and it is completed with a two-step occlusion culling process to preserve the self-occlusion effect. The approach is evaluated on RGBD images of real world 3D scene and the the reconstructed images from the CGH demonstrate the effectiveness of the proposed approach.
